Title : Medicine in the final frontier: How healthcare will shape humanity’s future in low earth orbit
Abstract:
Background: As humanity advances toward sustained low earth orbit presence, lunar habitation and future crewed missions to Mars, healthcare delivery and biomedical innovation will become essential pillars of long-duration space exploration. The expanding cadence of commercial and governmental aerospace missions, combined with increasing efforts to democratize access to spaceflight, has created a growing need to redefine medical standards, operational readiness, and inclusivity in aerospace medicine. This presentation explores how space medicine is evolving to support diverse human participation Hewhile simultaneously advancing healthcare knowledge applicable to Earth-based medicine.
Overview: The session will review the physiological effects of microgravity on major organ systems, including cardiovascular, pulmonary, musculoskeletal, neurovestibular, and ocular function. Will discuss the clinical and operational challenges of delivering healthcare in extreme environments, including limited medical resources, altered physiology, delayed evacuation capability, and the need for adaptive medical systems during prolonged missions. A central focus of the presentation is the emerging role of inclusive aerospace medicine. Drawing from experiences in parabolic flight programs such as AstroAccess, the discussion highlights how individuals with physical, sensory, and mobility disabilities have successfully participated in simulated microgravity missions. Through adapted screening, risk stratification, and mitigation strategies, 76 individuals with disabilities were screened and 23 successfully completed parabolic flight missions involving lunar, Martian, and microgravity simulation profiles. Operational outcomes demonstrated high safety margins, minimal injury rates, and manageable motion sickness, reinforcing the concept that functional performance, not physical conformity, should guide future aerospace medical standards. Perspectives from parabolic flight operations, and commercial space flights, aerospace medicine experts, and astronaut accessibility initiatives will illustrate how inclusive design can expand human participation in space while improving safety and mission success.
Discussion: The presentation challenges traditional assumptions surrounding disability and performance in aerospace environments. By examining how microgravity alters human physiology for all participants, the discussion reframes spaceflight through the lens of adaptability, resilience, and functional capability. This is by analysing how insights from disabled flyers in zero-gravity simulation environments inform inclusive medical design, prepare future participants in long duration space missions and care delivery in space. Attendees will gain insights on how to improve healthcare delivery, patient resilience, and medical preparedness in extreme environments on Earth and in the final frontier.
